How AFFF Firefighter Foam Is Related to Immune System Disorders?

Firefighting foam cancer lawsuit

Aqueous film-forming foam (AFFF) is a vital tool used in industries and firefighting operations to put out fires effectively. It works by creating a film that covers flames, stopping them and preventing re-ignition. 

Research has shown that exposure to PFAS chemicals found in AFFF can have serious consequences on the immune system. For instance, these compounds may disrupt the normal functioning of the immune system, making individuals more susceptible to infections, allergies, and autoimmune disorders.

What Is AFFF Used For?

The primary purpose of AFFF is to rapidly extinguish and control fires involving flammable liquids, such as gasoline, jet fuel, and oil. Its ability to form a film helps smother the flames, preventing their spread and rekindling. This makes AFFF invaluable in firefighting operations where liquid fuel fires pose a significant hazard.

AFFF is used in various industries beyond firefighting, such as oil refineries, chemical plants, airports, and military facilities. Moreover, AFFF is also used in storage tank facilities and specific manufacturing processes involving volatile liquids.

How Does AFFF Harm Human Immune Function?

The immune function is compromised by AFFF mainly due to the presence of per- and poly-fluoroalkyl substances (PFAS) in its formula. PFAS are man-made chemicals recognized for their resistance in nature and possible negative health impacts. As AFFF with PFAS is applied and released, it can expose humans through ingestion, inhalation, or skin interaction, causing harm.

Studies suggest that PFAS exposure leads to immune suppression, reduced response to infections, and higher vulnerability. Moreover, PFAS is associated with an increased risk of autoimmune disorders, where the immune system mistakenly targets healthy cells.

What Are the Immune-Related Health Effects of PFAS?

The immune system is a crucial defense mechanism that safeguards the body from diseases and infections. However, exposure to per and fluoroalkyl substances (PFAS) has shown significant associations that impact immune system function and cause adverse effects on human health. 

Here’s how PFAS exposure can impact immunity:

  1. Immune System Disruption and Suppression

Epidemiological evidence shows that PFAS exposure can disturb the regular functioning of the immune system. This disruption results in a diminished immune response, causing immune suppression and lowering the body’s proficiency in combating infections. Moreover, these effects are worse on people with a genetic susceptibility to a weak immune system.

  1. Altered Immune Cell Communication

PFAS can interfere with the communication between immune cells, impairing their ability to coordinate and mount appropriate immune responses. This disruption can result in an imbalanced immune system that may struggle to respond to pathogens adequately.

  1. Modulation of Inflammatory Responses

Increased PFAS concentrations in the blood due to exposure have been shown to modulate inflammatory responses in the body. Inflammation is a critical immune response that helps fight off infections. However, prolonged or dysregulated inflammation caused by PFAS exposure can disrupt the normal immune response, potentially leading to chronic inflammation and associated health issues.

  1. Increased Susceptibility to Infections

Elevated PFAS levels in the bloodstream have been associated with a higher susceptibility to infectious illnesses, such as lower respiratory tract infections. The lower immune responses and decreased antibody production resulting from PFAS exposure can heighten an individual’s vulnerability to bacterial, viral, and fungal infection

  1. Impaired Vaccine Response

A compromised immune system resulting from AFFF exposure may lead to an altered vaccine response. Vaccines rely on the immune system’s ability to mount an appropriate response to generate immunity against specific pathogens. Therefore, immune suppression or reduced vaccine antibody response caused by AFFF exposure can potentially interfere with the vaccine’s effectiveness.

  1. Risk of Autoimmune Disorders

Epidemiological studies suggest a potential connection between PFAS exposure and autoimmune disorders. Autoimmune disease occurs when the immune system mistakenly attacks healthy cells and tissues. PFAS exposure may contribute to developing or exacerbating autoimmune conditions like rheumatoid arthritis, lupus, or autoimmune thyroid disease.

Who Is at Higher Risk of PFAS Exposure?

Individuals living in areas contaminated with AFFF or those with occupational exposure to firefighting foam are at higher risks of developing immune-related. The following groups may be more exposed to AFFF-related health concerns:


Firefighters regularly handle AFFF during firefighting operations, putting themselves at significant risk of exposure to PFAS in the foam.

Military Personnel

Military personnel, especially those involved in firefighting or training exercises that utilize AFFF, are also at a heightened risk of exposure to PFAS.

Industrial Workers

Workers in industries involved in the manufacturing, producing, or using chemicals, including AFFF, may face an increased risk of exposure to PFAS chemicals like PFOA and PFOS.

Airport and Aviation Workers

Workers in industries involved in the manufacturing, production, and distribution of firefighting foam may face an increased risk of exposure to PFAS.

Individuals Living near Fire Training Sites or Disposal Facilities

Communities near fire training sites or disposal facilities with AFFF usage or storage may experience increased exposure risks. Contamination of groundwater and surrounding environments can occur, potentially impacting nearby residents.

Consumers of PFAS-Contaminated Water

Individuals who drink water contaminated with PFAS may face exposure risks. Contamination of drinking water can result from industrial discharges, improper waste disposal, or proximity to areas where AFFF is frequently used.

Pregnant Women

PFAS compounds can cross the placental barrier, leading to prenatal exposure to the developing immune system of the fetus. Prenatal PFAS exposure has been associated with various health concerns, including:

  • Potential impacts on fetal growth
  • Immune system development
  • Long-term health outcomes

Genetically Susceptible Individuals

Specific genetic differences can affect how well a person can process or remove PFAS from their body, which could result in elevated PFAS levels and a greater likelihood of experiencing negative health effects.

What to Do if You Develop Autoimmune Diseases Due to AFFF?

Experiencing autoimmune diseases can be distressing for individuals who suspect that their health has been compromised. If you believe that AFFF exposure has led to the development of autoimmune diseases, you might find the following steps helpful to navigate the situation:

Step 1: Seek Medical Attention

The first and most crucial step is to seek medical care from qualified healthcare professionals who can diagnose and treat autoimmune diseases. Establishing a clear medical record documenting the condition and its potential connection to AFFF exposure is essential.

Step 2: Gather Documentation

Collect relevant medical records, including diagnosis reports, test results, and treatment plans. Additionally, record AFFF exposure history, including details about the exposure duration, frequency, and intensity.

Step 3: Consult with an AFFF Lawyer

Consider consulting with a firefighting foam lawyer specializing in toxic mass tort cases. They can provide legal advice tailored to your situation and assess the viability of a potential firefighting foam lawsuit.

Step 4: AFFF Lawsuit Evaluation

If your firefighting foam attorney believes there may be a case, they can guide you through evaluating the merits of the AFFF lawsuit. A lawyer will consider factors such as the strength of the scientific evidence linking AFFF exposure to your autoimmune diseases, the applicable laws and regulations, and the potential liability of relevant parties.

Step 5: Take Legal Actions

Depending on the circumstances, your firefighting foam lawyer may recommend pursuing legal actions such as filing an AFFF lawsuit against responsible parties. This may involve seeking compensation for medical expenses, pain and suffering, loss of income, and other damages resulting from your autoimmune disease related to AFFF exposure.

Step 6: Join a Class Action Lawsuit

In some cases, individuals with similar claims may join a class action lawsuit. This allows a group of plaintiffs to collectively seek compensation for damages caused by a common issue, such as AFFF exposure and resulting autoimmune diseases.
